Jun 15, 2021 to Oct 23, 2026

Model Insight

With persistence 0.993, volatility shocks have a half-life of 104 trading days (~0.4 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 3.76 degrees of freedom, capturing fatter tails than a normal distribution.
